Virtual DataPort allows directly querying wrappers (without having to
define base relations on them). To do it, use the statement QUERYWRAPPER.
You have to provide the type and name of the
name and optionally, a list of conditions in the format
<value>,binaryoperator,<value> (see the syntax of condition
values in the section Syntax of Functions and Condition Values). Unary
operators and multivalued binary operators are not allowed.

See below the syntax to query WWW wrappers.
This syntax is slightly different than for the other types of wrappers. Only a list of key=value pairs can be indicated,
which will be directly received by the wrapper as input parameters.
